The 16th annual American Craft Council show gets underway in St. Paul tomorrow. More than 250 artists will display their work, and that includes glass artists Jim and Renee Engebretson. They work as a team-- Jim blows the glass and Renee etches a variety of patterns and designs into the glass. I visited the couple at their home studio in Hudson, Wisconsin. Jim Engebretson says he started working with glass back in 1968.
